Product Description:

Left-handed anchor rods, for roadway support, are characterized by high strength, reasonable structure and large preload force. Left-handed anchor can increase the binding force on the surrounding rock, and the installation is mechanized, which is easier and faster. Lefty anchors can be end anchors, extension anchors and full anchors. According to the steel grade, the left-hand anchor is classified as MG335/MG500/MG600, and the diameter of the rod body is from 16mm to 22mm, which can also be processed according to the construction requirements. Left-handed anchors are made of rods and accessories of different strengths and are used together with resin anchors. According to the designed anchoring length, the rod body is inserted into the hole where the anchoring agent is placed, and after stirring, the anchoring agent produces chemical reaction, and within a certain time, the rod body is bonded with the coal rock and fixed to the rock wall, and the threaded end of the threaded end is added with the protective net and the bearing tray, and then tightened with the nut to achieve the role of support, which can effectively form the high-strength pre-stressing support that can control the stability of roof slab, adapt to the movement of the peripheral rock, and reduce or even eliminate the off-layer, solve the problem of the roof slab, and even eliminate the problem of the roof slab, which is the most important factor for the stability of the roof slab. It can effectively reduce or even eliminate the separation of layers and solve the problem of roof collapse. It consists of a variety of support forms and structures to form a prestressed support system, which realizes the mechanical installation and greatly improves the safety and reliability of the support.

Specification

The working principle and installation and use steps of this left-hand anchor are as follows:

Working Principle:

1.Left-handed anchor is a support system composed of metal rod body, matching resin anchors and accessories.

2. According to the design requirements, the metal rod body is inserted into the holes through the pre-buried anchoring agent.

3. The anchoring agent is mixed with the metal rod body in the hole through agitation, and the anchoring agent undergoes a chemical reaction, which bonds the metal rod body to the coal rock and fixes it in the rock wall.

4. Install protection net and bearing tray at the threaded end of the metal rod body, and tighten it with nut to achieve the supporting function.

5. The high-strength prestressing support formed in this way can stabilize and control the roof plate, adapt to the movement of rocks, reduce or eliminate the phenomenon of layer separation, and solve the problem of roof collapse.

Installation:

1. According to the actual need to choose the appropriate specifications of the metal rod body and anchoring agent.

2. Drill holes on the anchoring substrate according to the designed hole diameter and depth to ensure that it matches the specifications of the anchor rods.

3. After drilling, remove the floating dust in the hole, and then put in the anchoring agent.

4. Use the mixer tool to drive the metal rod body, mix and push it to the bottom of the hole, the mixing time should be completed before the anchoring agent gel time.

5. During the waiting time, make sure the metal rod body does not move.

6. After waiting for the specified time, install the pallet, tighten the nut, and carry out the tensile strength test after reaching the bearing time.

The above is the working principle of the product and the steps of installation and use, hope it is helpful to you. If you have any further questions or need guidance, please feel free to contact me. I wish you a smooth operation!
